  The National Synchrotron Light Source II (NSLS-II) is a state-of-the-art 3-GeV third generation light source currently under construction at Brookhaven National Laboratory. The first part of the Linac to Booster Transport (LBT) line has been installed for the linac commissioning. This part will be used for the linac acceptance test. In this paper, we describe the preparation of the LBT sub-system integration test and the high level applications.

For a complex accelerator such as the Facility for Rare Isotope Beams (FRIB), a transfer matrix based online model might not be sufficient for the entire machine. On the other hand, if introducing another modelling tools, physics applications have to be rewritten for all modelling tools. A platform which can host multiple modelling tools would be ideal for such scenario. Furthermore, the model platform along with infrastructure support can be used not only for online applications but also for offline purposes with multi-particle tracking simulation. In order to achieve such a platform, a set of common physics data structures has to be set. XAL's accelerator hierarchy based data structure is a good choice as the common structure for various models. Application Programming Interface (API) for physics applications should also be defined within a model data provider. A preliminary platform design and prototype is discussed.

The High Level Applications (HLA) for NSLS-II commissioning is a development in progress. It is in a client-server framework and uses Python programming language for scripting and graphical user interface application development. This new development provides both scripting and graphical user interface (GUI) controls. The services developed in controls group provide name server, archiving, machine snapshot etc. The clients are developed mainly in the physics group and have measurement, analysis and modeling capabilities.
